Apex Pro I.S. (Intrinsically Safe version of the Apex Pro).Please consult Casella CEL for information about upgrading a standard model to an Apex Pro or an Apex I.S.to an Apex Pro I.S. The instrumentation is available as individual pumps or as complete kits with the

appropriate accessories to suit particular applications and is supported by our training and service facility atBedford.

The Apex was developed to provide sampling capabilities between 5 ml/min and 5 l/min (4 l/min for I.S.versions), suitable for a wide range of applications including solvent fumes, asbestos clearance andpersonal sampling of dusts. Apex pumps are ideally suited to many of the Total and Respirable dustsampling techniques detailed in the U.K. Health and Safety Executives publication MDHS14, and in otherreference methods.The information contained in this handbook relates only to the operation of Casella CEL sampling equipmentand is not intended to advise or influence your adopted sampling strategy. For advice on appropriate

sampling methods, refer to local legislation and guidelines as dictated by the relevant national and regionalhealth and safety organisations.

2. PREPARATION FOR USEThe following steps are required before the instrument can be operated.

Charge the Battery,Perform a Calibration,Connect the Sampling Head.

Manual operation is described in Chapter 4.

2.1 Charging the Battery


12/40

DO NOT open the battery compartment of I.S. versions in a hazardous area.DO NOT charge I.S. battery packs in a hazardous area.

The battery pack is installed in a compartment located at the bottom rear of the instrument (Figure 4) Acaptive screw locks the compartment cover.

There are two types of charger for non I.S and twotypes of charger for I.S units. The single-way FastCharger (Part No. 182052B) and the 5-way chargers fornon I.S. use listed in Section 8.3 can be used only for

non I.S. versions. It will not charge I.S. versions.I.S. versions must be charged only with thesingle-wayI.S. Charger (Part no. 182261B) or the 5-way chargersfor I.S. use listed in Section 8.3. For compliancereasons, these chargers accurately control currentduring charging, so take a slightly longer time to chargethe battery pack. These chargers can be used with nonI.S. versions, but will take longer to achieve a fullcharge.

Charging is accomplished by inserting the completeApex unit into a drop-in charger (see Figure 5). Allbattery chargers for Apex sampling pumps areintelligent units with a safety time-out and standbytrickle charge mode to keep the pump ready for use.

The use of modern fast charge technology enables a discharged non I.S. pack to be fully recharged within 3hours. Depending on filter type, a 1 hour charge can give a non I.S. pack sufficient power for 8 hoursoperation. Similarly, a discharged I.S. pack can be fully recharged within 4.5 hours and depending on filter

type, a 1.5 hour charge can give it sufficient power for 8 hours operation.A two colour LED on the charger shows the charging state. A constant red indicates that charging is takingplace while a constant green indicates that the full charge is being maintained by a trickle charge. (If neithercolour is shown while the pump is in the charger, a fault condition exists.)

When an Apex unit is initially placed in the charger unit, the LED will flash red for a few seconds beforechanging to constant red. If the battery has been deeply discharged, it is possible that the LED will continueto flash red for a longer period as the charger unit tries to condition the battery before entering the fastcharge state. If the flashing red continues for a prolonged period (e.g. a few hours) then a fault conditionexists. If when an Apex unit is placed in the charger, a constant green LED is shown, remove the Apex for

at least five seconds, then re-insert it. Faster replacement may have caused a false status indication.To ensure the maximum life expectancy of rechargeable battery packs, DO NOT allow them to remain in afully discharged condition for extended periods of time.When changing dry-cells in a non-rechargeable pack, it is recommended not to unplug the connector for thebattery pack lead.

The following additional instructions must be read when using Apex Lite Pumpversions.

WARNINGS !

Apex Lite Versions are not intrinsically safe and must not be used in Hazardous Zoned

areas.

Batteries and charging:

Apex Lite versions operate from 4 x AA

dry cell batteries, so no charger is required.

AA sized NimH rechargeable cells can alsobe used in the holder if preferred but no

charging will take place if the units are

placed in the Apex charger base

(182052B).

To convert the Lite version to a

rechargeable version purchase therechargeable battery pack 182073B insert

in place of the dry cell battery pack and

place in charger base 182052B.

Do not insert pump using dry cells into any recharging base.

8. Press any key to return to Hold Mode.The whole duration is stored as a single sample (run) with each ON / OFF sequence of the pumpincluded as a discrete event.

4.2 User Program Modes

This allows complex sampling schedules (created using the Pump Manager PC software and downloaded

via the infrared transducer) to be run by the pump. Two user programs can be stored: Pr1 and Pr2.This mode is ideal for taking samples where an operator spends time working in different parts of the siteand a separate exposure at each location must be determined. For example, an operator may spend 4 hoursworking in a quarry, take 1 hour for lunch, work 3 hours near a crusher and a final 1 hour in a workshop. Thework schedule can be set as a user program, with samples taken and stored for the separate periods.1. Enter Configuration Mode, select Program Mode / ON and accept it

as described in Section 2.4.The instrument reverts to Hold Mode.

2. Press or several times until the required program, Pr1 or Pr2 blinks on thedisplay.

Once the run is completed, the display will show the symbol and a PROGEnd message.6. Press any key to return the pump to Hold Mode.

7. When it is required to terminate the program early, press and hold to show the STOP option,then keep the key pressed until the pump reverts to Hold Mode.The whole duration is stored as a single sample (run) with eachON / OFF sequence of the pumpincluded as a discrete event.

5. CALIBRATION MODEThis mode is intended primarily for factory use during manufacture and servicing. This is a two pointcalibration which ensures that any selected flow rate will be as close as possible to the true value.It is suggested that this procedure might be employed by the user ONLY when it is suspected that theprimary calibration has been disturbed. Therefore only a brief description of the procedure will be given.

Caution !Use this procedure with caution, it changes the basic calibration for the ENTIREflow range of the pump.Attach a sampling head and flowmeter to the pumps inlet nozzle to measure the actual flow as shown inFigures 6 - 8 in Section 2.3.

1. Enter CAL SET from Configuration Mode.A display message asks for the lower calibration point to be set.


21/40

A display message asks for the upper calibration point to be set.

6. Use and to set the flow required at the calibration point.

The instrument will restrict the actual range in which the upper calibration can be set.

7. Press to accept the setting. The pump will start.

8. Use and to adjust the actual flow measured by the flow meter to match the setpoint.

9. Press to accept the upper setting.

The instrument uses these points to recalibrate the entire flow range. This calibration can then be fine-tuned during normal use by making single point flow calibrations at specific flows as in Set Flow.

6. PUMP MANAGER SOFTWARE6.1 Pump Manager IntroductionCasella CEL Pump Manager application software is designed to be used with the Casella Apex Pro andApex Pro I.S. range of personal air sampling pumps and offers a convenient way to store, manage andpresent sample data.This software allows the Duration, TWA and User Program Modes of Apex Pro pumps to be programmed.In addition, it saves sample results together with extra information related to the sample, and printscomprehensive reports.Communication between the PC and pump is via an infrared transducer. Once the infrared transducer hasbeen connected to a PCs serial (RS232) port there will be no need to connect (and disconnect) cablesbetween instrument and PC to facilitate communication. This eliminates wear and tear on any connectorsand cables. All infrared communication is fully error checked to prevent data corruption.

The software must be installed (Section 6.2) and infrared communication established(Section 6.3) before data can be downloaded from an Apex Pump to a PC.Pump Manager can be left running in the background on the Windows system as an icon. When a pumpcomes within range of the infrared computer link, the application will wake up and download data from thepump and store it in a database. It is possible to configure Pump Manager to start up in backgroundscanning mode when Windows starts, thus minimising the amount of user intervention required.

All data is stored in a database and identified according to the Apex pump from which it was downloaded,and optionally by details of the person who used the pump. This helps to maintain traceability of data. Alldata is automatically stored when it is changed, so if you have a system failure (e.g. power failure) youshould not lose any data.
